Hydroconductive action is controlled by Darcy’s Law that defines the ability of a fluid to flow through porous media. Fluid can move from wetter to drier – even against gravity. This explains how water can be transported from the roots of a tree to the leaves. Drawtex is a super-absorbent dressing that works against gravity. The Leva Fiber Electrostatic action occurs when the negatively charged Drawtex wound dressing comes into contact with the wound exudate.
Use systemic antibiotics together with either an alginate or alginate alternate dressing, or a polysaccharide iodine dressing, or an antibacterial fibre, or a silver dressing, or medicinal honey, or an amorphous hydrogel covered by a foam dressing.Ions from the exudate form a mobile layer of the opposite charge known as the electric double layer, effectively reversing the charge on the surface of the dressing to become positive. This allows the dressing to draw out a relatively large amount of exudate, devitalised tissue, bacteria and deleterious chemical mediators. It was assumed that because contact with wound fluid was beneficial to the healing process in acute wounds, the same approach should be applied to chronic wounds.It is now known that chronic wound fluid contains substances detrimental to cell proliferation, and maintaining contact between a chronic wound and its fluid is likely to delay healing.The amount of wound drainage that a patient exudes is largely depends on the type of wound and the individual.
